• Introduction The HGD-300A marine engineering geological survey drilling rig is a long stroke power head type drilling rig. The power head rotation adopts frequency conversion speed regulation technology, equipped with a 12 meter drilling tower and a lifting and sinking balance mechanism. It can drill in waves below level 5 at a depth of 100 meters, and can also be used for water geological survey construction and pile foundation engineering construction in rivers and lakes. The main unit can also be used as a land foundation engineering construction drilling rig.
  
  Main features ● The drilling rig power head adopts variable frequency speed regulation, and the mechanical power head provides a long process, compact structure, reasonable layout, and wide speed regulation range, which can meet the needs of drilling in various complex formations.
  ● Set up a safe and reliable power head anti fall mechanism to ensure the safety of equipment and personnel.
  ● The drilling rig is equipped with a fine-tuning drilling mechanism, which facilitates balanced drilling.
  ● Equipped with a hydraulic pipe twisting machine, it realizes the mechanization of twisting and unloading drill rods, reduces labor intensity, and improves drilling efficiency.
  ● The power head of the drilling rig is moved back as a whole, making way for the opening of the hole. The operating space at the opening of the hole is large, making it convenient for drilling operations.
  ● The equipped bottom hole sampling equipment can meet the needs of taking rock samples from various complex formations.
